2nd Call for Papers - CODI 2021: 2nd Workshop on Computational Approaches to Discourse https://sites.google.com/view/codi-2021 Held in conjunction with EMNLP 2021 November 10-11, 2021   Update: Note that we accept double submissions, see the dedicated section below.

Important information: The CODI workshop organization should be hybrid, following the EMNLP program chairs’ decision: “EMNLP 2021 is currently officially scheduled to be held in hybrid mode, online and in Punta Cana, in the Dominican Republic. ”. The 2-days workshop will take place on November 10 and 11.

**Aims and scope** The last five years have seen a dramatic improvement in the ability of NLP systems to understand and produce words and sentences. This development has created a renewed interest in discourse problems as researchers move towards the processing of long-form text and conversations. There is a surge of activity in discourse parsing, coherence models, text summarization, corpora for discourse level reading comprehension, and discourse related/aided representation learning, to name a few. At this juncture, we envision that a workshop that brings together discourse experts and upcoming researchers will catalyze the speed and knowledge needed to solve such problems, as well as serve as a forum for the discussion of suitable datasets and reliable evaluation methods. The previous workshops on discourse in machine translation (DiscoMT), linking lexical, sentential and discourse semantics (LSDSem), discourse structure in natural language generation (DSNNLG), discourse parsing and treebanking (DisRPT) and coreference (CORBON/ CRAC), have shown that there is considerable interest and success in bringing together the community working on specific problems. We believe that the discourse community will also benefit from a general forum where work ranging from corpus development/analysis to computational models, and evaluation is discussed, and desiderata can be drawn for future progress. The Workshop on Computational Approaches to Discourse (CODI) brings together researchers interested in all aspects of discourse and its computational modeling. The first CODI workshop was held at EMNLP 2020 and showcased diverse discourse research (see the papers presented: https://codi-workshop.github.io/accepted-papers/).%C2%A0 This year, the workshop will also host two shared tasks: - CODI-CRAC - Anaphora Resolution in Dialogues: https://competitions.codalab.org/competitions/30312 - CODI-DISRPT2021- Discourse Relation Parsing and Treebanking: https://sites.google.com/georgetown.edu/disrpt2021   Please visit the corresponding websites for more information.

**Topics of interest** We welcome symbolic and probabilistic approaches, corpus development and analysis, as well as machine and deep learning approaches to discourse. We appreciate theoretical contributions as well as practical applications, including demos of systems and tools. The goal of the workshop is to provide a forum for the community of NLP researchers working on all aspects of discourse. Topics of interest include, but are not limited to:​​​​​- discourse structure - discourse connectives - discourse relations - annotation tools and schemes for discourse phenomena - corpora annotated with discourse phenomena - discourse parsing - cross-lingual discourse processing - cross-domain discourse processing - anaphora and coreference resolution - event coreference - argument mining - coherence modeling - discourse and semantics - discourse in applications such as machine translation, summarization, etc. - evaluation methodology for discourse processing

**Submissions** We solicit four categories of papers: (1) regular workshop papers, (2) demos, (3) extended abstracts and (4) shared tasks papers. Only regular workshop papers, shared task papers and demos will be included in the proceedings as archival publications. Regular papers must describe original unpublished research. Long papers may consist of up to 8 pages of content, plus unlimited pages for references. Short papers can have up to 4 pages, plus unlimited pages for references. Demo submissions may describe systems, tools, visualizations, etc., and may consist of up to 4 pages, plus unlimited pages for references. Accepted long, short, and demo papers will be presented orally. Extended abstracts can describe work in progress or those already published elsewhere. These may be two pages long (without references). Extended abstracts are non-archival. They will be presented orally, and included in the workshop program and handbook, but will not appear in the workshop proceedings. For shared task papers, please refer to the corresponding websites:- CODI-CRAC: https://competitions.codalab.org/competitions/30312#learn_the_details-overvi... - CODI-DISRPT2021: https://sites.google.com/georgetown.edu/disrpt2021/submission?authuser=0 Shared task papers will be presented during the dedicated sessions, either orally or as posters. They will be included in the workshop proceedings.  Final versions of all types of papers will be given one additional page of content.   **Double submission** We allow for double submissions. Please indicate during submission to which other conference or workshop your work has been submitted. We may also invite authors of papers accepted to the conferences (e.g. EMNLP, ACL) including Findings to present their work at the workshop. Please indicate whether your paper has been accepted to e.g. ACL during submission, or let us know by email that your paper has been accepted elsewhere (including Findings) upon notification. These papers will not be part of the proceedings of the workshop.

**Submission website** All submissions must follow the EMNLP 2020 formatting instructions described here: https://2021.emnlp.org/call-for-papers/style-and-formatting Please submit your papers using the link indicated on our website.
